Abstract
A method of manufacturing bistable strips having different curvatures, each strip including a plurality of portion of layers of materials, wherein at least one specific layer portion is deposited by a plasma spraying method in conditions different for each of the strips.
Claims9
A method, comprising:
- manufacturing a first bistable strip having a first curvature, wherein manufacturing the first bistable strip includes forming a first plurality of layers including a first layer of a first material, wherein forming the first layer includes depositing the first layer in a vacuum chamber by plasma spraying using a plasma spray system having a first set of deposition conditions that causes the first curvature;
- and
- manufacturing a second bistable strip having a second curvature different from the first curvature, wherein manufacturing the second bistable strip includes forming a second plurality of layers including a second layer of the first material, wherein forming the second layer includes depositing the second layer in the vacuum chamber by plasma spraying using the plasma spray system having a second set of deposition conditions that causes the second curvature, the second set of deposition conditions being different from the first set of deposition conditions.
